Lithium Orotate
A low-dose form of lithium bound to orotic acid for enhanced cellular uptake. At microdose levels (1–5 mg elemental lithium), lithium orotate demonstrates neuroprotective, anti-ageing, and mood-stabilising effects distinct from pharmaceutical lithium carbonate used in psychiatry.

What Is Lithium Orotate?
Lithium orotate is a salt of lithium bound to orotic acid. It is distinct from lithium carbonate, the pharmaceutical form used at high doses (600–1800 mg/day) to treat bipolar disorder. Lithium orotate is used at dramatically lower doses — typically providing 1–5 mg of elemental lithium per day — as a dietary supplement.
The orotic acid carrier is claimed to improve intracellular lithium delivery compared to carbonate, potentially allowing neurological effects at much lower doses and with a substantially better safety profile.
The Longevity Connection
Several lines of evidence connect low-dose lithium to longevity and neuroprotection that have made it increasingly discussed in longevity circles:
Population studies: Regions with higher natural lithium in drinking water consistently show lower rates of suicide, dementia, and all-cause mortality. A landmark Japanese study found inverse correlations between water lithium and Alzheimer's incidence across 25 municipalities.
Telomere data: Higher lithium exposure associates with longer telomere length — one of the most direct biomarkers of biological ageing.
Animal data: Low-dose lithium extends lifespan in C. elegans, Drosophila, and rodent models. The GSK-3β inhibition mechanism is particularly relevant to tau pathology in Alzheimer's disease.
Microdose vs Pharmaceutical Dose
The critical distinction: lithium carbonate in psychiatry is dosed at 600–1800 mg/day of the compound, providing ~110–330 mg elemental lithium. This requires regular blood monitoring due to narrow therapeutic window.
Lithium orotate supplementation targets 1–5 mg elemental lithium/day — approximately 50–100x lower. At these levels, the toxicity concerns associated with pharmaceutical lithium do not apply, though long-term human safety data at supplement doses remains limited.
